If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Immediately turn off the water supply and power if the dishwasher is overfilling.
- Observe valve behavior: With power off, if water continues to flow into the dishwasher, the valve is mechanically stuck open.
- Inspect for debris: Remove the inlet valve and check for debris lodged in the valve seat. Light debris may be cleaned out, but replacement is usually recommended.
- Check control output: If water only flows when power is on, but does not stop at the correct level, test the control board output to the valve for proper switching.
Repair action: Replace the water inlet valve if it leaks or sticks open. If the valve is good but the board continues to power it incorrectly, replace the main control board.
